How to tell if HPFP is leaking
I have a question for everyone that's familiar with the topic. I've had the p2188 code now for most of last year. I cleaned the connectors and changed the oil yesterday. For the road test I did yesterday after, it seems to have finally fixed the issue. I have been in contact with a member here and he told me to completely clean the contacts, change the oil and hopefully that would fix my p2188 code. While there was a raw gas smell coming from the oil, there was no "rainbowing" of the oil after it sat for about 2 hours, something I would have thought would have happened if the fuel in my oil was bad enough. I ran the car after changing the oil for about 20 minutes, came home and my HPFP tick was finally steady. However, when I went to smell my new oil, an odor of raw fuel was evident yet. Other then smelling my oil, is there any other way to check for fuel in my oil? After I've dealt with the weird HPFP tick for almost a year, is it possible that my HPFP seals are shot? Any thoughts or help on how to check for gas in my oil would be appreciated. Could it be a leaky injector and not the HPFP leaking? Would that cause a fuel smell in oil? Is this something the dealer will have to diagnose? I hate to throw a $350 HPFP on it and cross my fingers!!!
